STANCHION-ALINEMENT DEVICE.

Specification of Letters Patent.

Patented June 29, 1920.

Application filed December 26, 1919. Serial No. 347,274.

To all 1071 0722. it may concern: I

Be it known that I, Ronnnr F. RAsMUssnN, a citizen of the United States, and resident 0t Oshkosh, in the county of Winnebago and State of Wisconsin, have invented new and useful Improvements in stanchion-Alinement Devices, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

The present invention relates to certain new and useful improvements in stanchion alinement devices for adjusting the stanchion backwardly or fO'lWAIdlf] with respect to the gutter.

One object of the present invention is to provide an adjustable stanchion alining device so constructed that the adjustment cannot be changed. without first a lifting and then a turning movement of the stanchion support or swivel bolt.

A further object of this invention is to provide a stanchion aliner capable of ready adjustment and which is so constructeijl that the same may be produced at a comparatively smali cost all things considered.

lVith the above and other objects in view which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claims.

In the accompanying drawing, I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles thereof, and in which:

Figure 1 is an elevational View of an upper section of a stall frame and stanchion equipped with my alinement device.

Fig. 2 is a view, part in section and part in elevation, of my device, said view being taken on the line 2-2 of Fig. 3.

Fig. 3 is a bottom plan view of the stanchion aliner, and

Fig. 4t is a transverse sectional view through the alining device taken on the line 1% of Fig. 2.

Referring now more particularly to the accompanying drawing, 5 designates the vertical bars of the stall frame connected together at their upper ends by means of a transverse bar or rod 6; and 7, a stanchion pivotally secured at its upper portion as at 8 to the swivel stanchion supporting bolt 9 forming part of my stanchion aliner, to be described. 7

The aliner consists of a casing 10 having its bottom wall 11 provided with a plurality of spaced apart locking recesses or openings 12 connected together by means of slotted passageways 13. The passageways 13 are of a width slightly greater than the width of the lower flattened end of the swivel bolt 9 and of a width less than the diameter of the locking recesses 12, for the purposes hereinafter described. As best shown in Figs. 2, 3, and 4, the bolt 9 has its inner or upper end provided with an enlarged head 1 1 of a diameter greater than the diameter of the recesses 12, a rounded shank or portion 15 of a diameter slightly less than the locking recesses 12 whereby the same may be selectively engaged with the recesses 12 and be retained from movement longitudinally along the casing, and a pair of lugs or projections 15 formed on opposite sides of the bolt 9 adjacent the lower end of the rounded portion 15.

The rounded portion 15 of the swivel bolt 9 provides an annular flange or shoulder 14' for engaging the portion of the bottomwall 11 adjacent the periphery of the recess 12 in which the bolt is engaged. To move the bolt 9 from one recess to another the lugs 15' are registered with. the passageways 13, the bolt then moved into the casing until the lugs 15 are free of the passageways 13, when the bolt. is turned a quarter turn to bringthe flattened portion of the bolt in line with the passageways 13. The bolt is then moved to register with the recess 12 giving the desired adjustment, when the flattened portion is disengaged from the adjacent passageway 13, the bolt then turned so that the lugs 15 can drop beneath the passageway, see Fig. 4.

The casing 10 has its top closed by means of a cover 16 having depending flanges 17 for engagement with the side walls of the casing, and the cover is held in place by means of fastenings 18. The cover 16 has formed medially of its ends a raised portion or enlargement 19 provided with a V-notch or recess 20 for engagement with the transverse bar 6 which in the present instance is squared in cross section and cooperating with the V-notch 20 is a clamping plate 21 provided with an inverted V-notch 22 clamped against the bar 6 by means of fastenings 23.

While in the present instance, I have illustrated the notches 20 and 22 as being angular, it will be understood that the same may have any desired shape or form to conform with the transverse rod 6, and that the aline- Inent device may be adjusted on the bar 6 by loosening the fastening means 23 and sliding the same thereon. The cover 16 being readily removable permits the insertion of the swivel bolt 9 and also permits the easier production of the alinement device 1n that the same may be either cast or stamped.

WVhat I claim as my invention is:

l. A stanchion alining device comprising a support having a plurality of recesses therein, alined passageways of less width than the diameter of said recesses and connecting the same, a swivel bolt having a head movable to selectively engage said recesses, and means carried by the swivel bolt and engageable with the portion of the outer face of the casing surrounding the reeesses to normally secure the swivel bolt from movement from one recess to another. 2. A stanchion alining device comprising a support having a plurality of recesses therein, alined passageways of less diameter than said recesses connecting the same, a swivelbolt having a head of a diameter greater than that of said recesses and a rounded shank portion adjacent to the head and movable to selectively engage the recesses, a flattened portion depending from said rounded shank portion and of a thickness less than the width of said passageways, and a projection formed on the shank of said bolt intermediate the rounded poition and the flattened portion, said projecness less than the width of said passageways, and of a width greater than the diameter of the rounded portion of the shank to provide shoulders for engaging the support when said'flattened portion is not alined with the passageways, and projections intermediate said shoulders and the bolt head and preventing the movement of the bolt from one recess to another without first alining the projection with the passageways.

4. A stanchion alining device comprising a support having a plurality of recesses therein, alined passageways of less diameter than said recesses connecting the same, a swivel bolt having a head of a diameter greater than that of said recesses and a rounded shank portion adjacent to the head movable to selectively engage the recesses, a flattened portion depending from said,

rounded. shank portion and of a thickness less than the width of sa1d passageways, and oi a width greater than the diameter of the rounded portion of the shank to provide shoulders for engaging the support when sa1d flattened portion is not alined with the passageways, pro ectlons spaced from the bolt head and said shoulders a distance slightly greater than the thickness of said.

support, said projections being alined with said passageways and the bolt then raised and turned to aline the flattened portion and then raised to permit the same to be moved from one recess to another.

5. A stanchion alining device comprisinga swivel bolt having a head of a diametergreater than that of sa1d recesses and arounded shank portion adjacent to the head movable to selectively engage the recesses, a flattened portion depending from said rounded shank portion and of a thickness less than the width of said passageways,

and of a width greater than the diameter of the rounded portion of the shank to provide shoulders for engaging the support when said flattened portion is not alined with the passageways, projections spaced from the bolt head and said shoulders a distance slightly greater than the thickness of said support and arranged at right angles with respect to said flattened shank portion.

In testimony whereof I affix my signature.
